High-speed and high-resolution optical coherence tomography (OCT) is a powerful technology that enables the performance of optical biopsy, the in situ imaging of tissue morphology in vivo and in real time. OCT imaging constructs cross-sectional images by measuring echo delay and the intensity of optical backscattering from internal tissue structures. Femtosecond solid-state lasers are a powerful enabling technology for performing OCT because they have short pulse durations, resulting in short coherence lengths, and are tunable across a range of wavelengths. Femtosecond lasers can produce high average powers and thus enable real-time imaging.
